An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-42893 in the wild and no public exploit code.\n\nAffected product: Microsoft Outlook. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-42893/ (Markdown: https://insights.sbomify.com/CVE-2026-42893/index.md)","id":"CVE-2026-42893","markdown":"https://insights.sbomify.com/CVE-2026-42893/index.md","name":"CVE-2026-42893","record":{"aliases":["GHSA-h35m-vhjw-vqxj"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Outlook iOS","requires_auth":"none","summary":"An attacker can perform tampering via command injection in Microsoft Outlook for iOS, requiring a patch to mitigate the risk.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"outlook","vendor":"microsoft"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"Improper neutralization of special elements used in a command ('command injection') in M365 Copilot allows an unauthorized attacker to perform tampering over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Microsoft Outlook for iOS Tampering Vulnerability","id":"CVE-2026-42893","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:outlook","products":["microsoft:outlook"],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Copilot Tampering Vulnerability","id":"CVE-2026-42895"},"packages":[],"prev":{"headline":"Microsoft Edge (Chromium-based) for Android Spoofing Vulnerability","id":"CVE-2026-42891"},"products":["Microsoft Outlook for iOS"],"published":"2026-05-12","related":[{"cvss_score":7.8,"headline":"Microsoft Office Outlook Security Feature Bypass","id":"CVE-2017-11774","kev_date_added":"2021-11-03","published":"2017-10-13"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2001-0538","kev_date_added":null,"published":"2002-03-09"},{"cvss_score":9.3,"headline":"Use after free in n/a","id":"CVE-2013-3870","kev_date_added":null,"published":"2013-09-11"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2010-2728","kev_date_added":null,"published":"2010-09-15"},{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2010-0266","kev_date_added":null,"published":"2010-07-14"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2003-1378","kev_date_added":null,"published":"2007-10-19"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2007-4040","kev_date_added":null,"published":"2007-07-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Microsoft"]},"summary":"An attacker can perform tampering via command injection in Microsoft Outlook for iOS, requiring a patch to mitigate the risk.","url":"https://insights.sbomify.com/CVE-2026-42893/"}
